My nephew has gotten 2 deer using my loads, but they were out of a Ruger 77/44 rifle, so I'm not sure how much it will help, as they were going about 1,650 fps. (270grain). The first deer was @ 90 yds. shot on the point of the shoulder, full diagonal penetration with a 2-1/2" exit by the rear hip. Second deer at 60 yds. broadside, behind the shoulder shot, full penetration, 2-1/2" exit. Neither deer moved. I have been trying to get my nephew to try hardcast bullets, but after these 2 deer, he wants nothing but the Gold Dots.
